UNITED fsTATE- s 4PATENT oFI'fICEQv T 0 all whom t may concern:

` Be it known that I, Jon DINES, a citizen of the United States, residing at`lTempe, in the county of Maricopa and State of Arizona, have invented new and useful Improvements in Gin Legs, ofj'which the following is a specification.v n

This invention relates to an adjusting leg for the knife of a roller type gin stand, onel object being to prevent variation in the length of the leg after adjustment has once been effected, special provision being made for adjustment due to wear.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangement of` elements described, illustrated and claimed, it being understood that modifications may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings, Figures 1 and 2 show the complete device, from different sides; Figure 3 is a section on line-3 3 of Figure 2; Figures 4 and 5 are detail views of the device in which the adjusting wedge is mounted; Figure 6 is a detail view showing the mounting of a reduced bearing block and its relation to a U-shaped inclosing member having a spacing element therein.

In carrying out the invention, I provide a one piece casting 10, preferably of aluminum, for connection with each end of an adjusting rod 12, the ends of the rod being provided with right and left hand threads entering threaded sockets 13 formed on the casting. The rod is provided with an angular central portion 14 by meansl of which it is rotated for eii'ecting adjustment, and lock nut-s are designated 15 and 16.

The castings 10 are of the form shown in detail in Figures 1 andv 3, and eachcasting includes an extension 17 through which a wedge adjusting rod 18 passes, the rod being retained by lock nut 19 and by nut 20 at the end thereof.

A U-shaped element 23 of steel is provided with laterally and upwardly extending ears 24 and is secured by bolts 25 to each casting 10. The element 23 encloses a correspondingly shaped element 26formed of so-called Never-burn brake lining, anda bearing block 28 has aA concave socket 29 and is retained in position by means ofk a bolt 30 passing through slot 31. Each element 23 is offset to form shoulders 5 against which Application inea February ze, 1923. seria1'N0.'e2'1,4as.

the ends of the lining 26 abut, and a rivet 26 prevents the lining from slipping.

This provides for an adjustment of threeeight-s of an inch', due to wear onthe block. n

A rectangular block 34 is located as shown,

and a tapered block 35 is separated therefrom by a shim 36. Cooperating'with this tapered block is a wedge 37, through which adjusting rod 18 passes, and an additional block 38 is located on the opposite side of the wedge. The `casting 10 is provided with slot 10 leaving a space of an inch as shown, for removing the shim and the tapered block.

This arrangement is duplicated in the other casting 10, it being understood that the two legs of this construction are employed for each moving knife. The other U-element of the particular leg under discussion accommodates a crank shaft ybetween .the lining and the bearing block 2,8. block may be reduced in thickness as shown in a separate view at 28",.if the crank shaft has becomel considerablyy worn, and in that event the U-element 23 will be formed or attached in such manner as to provide less space between the parallel walls thereof, in

order to iit'the block snugly. The element j23l of resilient steel readilyV accommodates itself either to a worn crank or a new shaft of less diameter than that usually employed. A grease cup is shown at 40. v l

It may be added that the casing 10 constitutes a'type of frame for mounting the wedges and the associatedl elements, and hence the elements 28 and 28 and the inclosed devices will be referred to as a twopart bearing. In the case of a worn crank shaft, a sub-lining, or additional strip 7, is employed as a spacing element.

What is claimed is i 1. In a device of the class described, a rod, wedge mounting means adjustably connectedtherewith, a U-shaped member connected with the mounting means, a bearing The provide a bearing. means transmitting pressure from the wedge to the block, and means for adjusting the wedge transversely of the block and rod, said bearing block being cut i away at the sides thereof permitting the elements of the U-member'to approach each other under pressure, for t-aking up wear.

2. In a device ofy the class` described, a

rod, a frame including a socket portion havv ing adjustable connection With the rod, a two-part bearing element eonneted with the frame, one jof the paits being'a-Kdjiistdole,A a wedge adjustable transversely of theframe and rod, means for looking the Wedge' in 15 ,element on opposite ysides thereof.

3. In e device ot the ,dass described, `a

rod, a frame including a socket portion having adjustable @Onneeten with the rod, a liwfefdge *adj'ilstebjle t1"ellis?eisely of theI frame andmrodf sjaoedre1erneute*` n opposite sides of "the Wedge, a bearing block adjustable upon the transverse movement of the Wedge, means inelosng the bearing block and ooojoerating with one end thereof for forming a complete begiingen extension carried by the freni@v any edjustble rod passing through the Wedge and thioughseid extension, and means engaging tjheod endeXil? for maintaining" the ,adj ustnent of the 'YS/edge.

In testimony whereof I ethic my s*ignvtiuge.
